Mode 2: 8-bit Compare Counter with 4-bit Programmable Prescaler
Mode 3/4: 8-bit Compare Counter and 4-bit Programmable Prescaler
4-bit compare
4-bit counter
4-bit register
The 4-bit stage is used as programmable prescaler for the 8-bit counter stage. In this mode, a
duty cycle stage is also available. This stage can be used as an additional 2-bit prescaler or for
generating duty cycles of 25%, 33% and 50%. The 4-bit compare output (CM1) supplies the
clock output (POUT) with clocks.
Figure 22-12. 4-/8-bit Compare Counter
In these modes the 4-bit and the 8-bit counter stages work independently as a 4-bit prescaler
and an 8-bit timer with an 2-bit prescaler or as a duty cycle generator. Only in the mode 3 and
mode 4, can the 8-bit counter be supplied via the external clock input (T2I) which is selected via
the P4CR register. The 4-bit prescaler is started via activating of mode 3 and stopped and reset
in mode 4. Changing mode 3 and 4 has no effect for the 8-bit timer stage. The 4-bit stage can be
used as prescaler for Timer 3, the SSI or to generate the stop signal for modulator 2 and
modulator 3.
